+==============================================
+Welcome to the Senlin developer documentation!
+==============================================
+
+Senlin is a service to create and manage :term:`cluster` of multiple cloud
+resources. Senlin provides an OpenStack-native ReST API and a AWS 
+AutoScaling-compatible Query API is in plan.
+
+What is the purpose of the project and vision for it?
+=====================================================
+
+* Senlin provides a clustering solution for :term:`OpenStack` cloud. A user
+  can create clusters of :term:`node` and associate :term:`policy` to such
+  a cluster.
+* The software interacts with other components of OpenStack so that clusters
+  of resources exposed by those components can be created and operated.
+* The software complements Heat project each other so Senlin can create and
+  manage clusters of Heat stacks while Heat can invoke Senlin APIs to 
+  orchestrate collections of homogeneous resources.
+* Senlin provides policies as plugins that can be used to specify how clusters
+  operate. Example policies include creation policy, placement policy,
+  deletion policy, load-balancing policy, scaling policy etc.
+* Senlin can interact with all other OpenStack components via :term:`profile`
+  plugins. Each profile type implementation enable Senlin to create resources
+  provided by a corresponding OpenStack service.
+
+This documentation offers information on how Senlin works and how to 
+contribute to the project.
